Urbanization effects on the food-water-energy nexus within ecosystem services: A case study of the Beijing-Tianjin-Hebei urban agglomeration in China

Ecological Indicators, Год журнала: 2024, Номер 160, С. 111845 - 111845

Опубликована: Март 1, 2024

This research centers on the necessity for synchronized management of natural resources in urban agglomerations. study utilizes ecosystem services theory to analyze interplay between land use and Food-Water-Energy (F-W-E) nexus Beijing-Tianjin-Hebei (B-T-H) region from 2000 2030. Assessment is conducted using InVEST models, which include Habitat Quality (HQ), Water Yield (WY), Carbon Sequestration (CS), Soil Retention (SDR), Food Production (FP). The findings indicate an annual increase construction with a concurrent notable decrease cultivated land. Furthermore, HQ, CS, per capita FP show decline until 2020, expected continue Conversely, WY SDR have been growing annually, albeit projected by Spearman coefficient analysis uncovers synergies HQ alongside trade-offs CS WY. Trade-offs are also observed SDR, HQ. Applying K-means clustering facilitates county-based spatial planning F-W-E system, providing crucial insights suggestions sustainable resource management.

Exploring the Relationship Between Land Use and the Food‐Water‐Energy Nexus: Insights From A Systematic Literature Review

Land Degradation and Development, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

ABSTRACT As urbanization accelerates, cities face increasingly significant ecological challenges essential for sustainability. One of the primary manifestations these is imbalance between food, water, and energy resources, often resulting in irrational use land. However, few scholars have reviewed relationship land F‐W‐E nexus. Thus, this paper examines interplay Food‐Water‐Energy nexus using a thematic literature review covering past 9 years (2015–2023). Specifically, 88 relevant articles been identified encoded NVivo software based on structured coding framework that focuses theory (framework), method, indicators, spatial scale, aims, results. The was retrieved keyword searches from Web Science databases. follows systematic four‐step process: defining sub‐questions, conducting PRISMA guidelines, utilizing organization, finally synthesizing discussing findings. findings reveal several key insights: (1) Ecological urban morphology studies are understanding planning patterns. influence agricultural water quality remains ambiguous, discrepancies exist effects land‐use intensity residential density F‐W‐E. (2) There clear lack comprehensive interdisciplinary multi‐objective research theories methods F‐W‐E‐L (Food‐Water‐Energy‐Land use). At same time, implicit consumption beyond geographical boundaries needs attention. (3) Sustainable development goals within system clearly defined goalsover time fail to differentiate across scales. (4) deficiency shared decision‐making post‐policy tracking framework. To address challenges, comprehensive, multi‐scale, approach proposed, integrating multi‐sectoral public participation into planning.

Promoting low-carbon land use: from theory to practical application through exploring new methods

Humanities and Social Sciences Communications, Год журнала: 2024, Номер 11(1)

Опубликована: Июнь 4, 2024

Abstract Cities are main carbon emissions generators. Land use changes can not only affect terrestrial ecosystems carbon, but also anthropogenic emissions. However, monitoring at a spatial level is still coarse, and low-carbon land encounters the challenge of being unable to adjust patch scale. This study addresses these limitations by using land-use data various auxiliary explore new methods. The approach involves developing high-resolution model investigating patch-scale integrating high sink/source images with Future Use Simulation model. Between 2000 2020, results reveal an increasing trend in both sinks Shangyu district. Carbon offset approximately 3% total Spatially, north exhibits net emissions, while southern region functions more as sink. A 14.5% area witnessed change type, transfer-out cropland constituting largest 96.44 km 2 , accounting for 50% transferred area. Land-use transfer resulted annual increase 77.72 × 10 4 t between 2020. Through structure optimisation, projected 7154 C/year from 2030, significantly lower than amount Further optimisation scale enhance sink 129.59 C/year. conclusion drawn that there considerable potential reduce through control. methods developed our effectively contribute contexts support use, promoting application theory practice. will provide technological guidance planning, city so forth.

Chinese megacities face significant challenges in reducing carbon emissions while balancing economic growth and social welfare. This study constructs an innovative multi-objective optimization model, the SD-NSGA-III integrated with a System Dynamics (SD) model using Non-dominated Sorting Genetic Algorithm III (NSGA-III) to optimize resource allocation Beijing. The targets environmental, economic, goals by establishing water–land–energy–carbon (WLEC) nexus for analyzing strategies reduction pathways under various constraints. Scenario simulations efficiency-oriented scenario indicated potential energy of 81.4% 2030. fairness-oriented revealed trade-offs between equity emission reductions, emphasizing need balanced strategies. Introducing constraints on resources significantly reduced median 80 million tons These findings demonstrate effectiveness providing actionable achieving neutrality sustainable development cities.

Land, Год журнала: 2024, Номер 13(6), С. 813 - 813

Опубликована: Июнь 6, 2024

The matching relationship between water and land resources in the karst mountains is closely related to regional ecological environmental security, human well-being, high-quality socio-economic development. Based on a massive literature review, this review systematically summarizes research overview, development process, mechanism of resources. results show following: (1) Since 1990, number publications has shown steady upward trend, with journals covering multiple fields, characterized by multidisciplinary interdisciplinary features. (2) mountainous areas experienced three stages: “single element–binary matching–multiple coupling”. It reveals evolutionary process from focusing single internal system mutual resources, then study coupling other external systems. (3) coordinated depends joint interactions natural, economic, social factors, while mainly focuses around aspects agricultural production, environment, economic Furthermore, proposes that future should explore through theoretical framework construction, model innovation, scale refinement, analysis. expected will provide scientific reference for advancing optimizing their management.
